We have a WIN2012 R2 server (3 x SSD 1T each, 1 x SATA 2TB), each drive is being put on it's own RAID (reads 4 "Adaptec Array SCSI Disk Device) on device manager in windows "disk drives" section
suddenly the (1 x SATA 2TB) disappeared, we tried hard with company's support, they told us the drive is (dead and unrecoverable).
we logged on the server from KVM, and choose the RAID application from BIOS before OS load, it shows that the Array is healthy, we went further to disk check tool which is a part of the RAID bios program, and hit verify disk media on it, it began checking sectors normally!
after checking about 40%, it stopped with (error) message
unexpected sas command failed / sense key 0Eh - Miscompare / Sense Code: 00h
but driver does not show on windows, and device manager now show only 3 "Adaptec Array SCSI Disk Device" items in "disk drives"
1- could we restore the drive normally? 2- if couldn't, can we retrieve the data on it?
can anyone give some instructions?
